Manticore Search 14.1.0: Force Bigrams and Bug Fixes

Published: Nov 07, 2025

We're pleased to announce Manticore Search 14.1.0 , a release that includes our work for October 2025. This update adds the force_bigrams option for spell correction, replication progress tracking, and various bug fixes.

❤️ Special thanks to @ricardopintottrdata for their contributions on HAVING total counts and filter error fixes, and to @jdelStrother for improving CJK segmentation handling when Jieba support isn't available.

⚠️ Important Replication Update

Version 14.0.0 updated the replication protocol. If you're running a replication cluster, you need to:

Cleanly stop all your nodes
Start the node that was stopped last with --new-cluster, using the manticore_new_cluster tool in Linux

New Features and Improvements

Force Bigrams Option

Added a force_bigrams option for fuzzy and autocomplete functionality. This option helps with spell correction for shorter words where trigram matching may not work as well. For example, when correcting "Geroge" to "George", bigrams can provide better matching than trigrams for such transposition cases.

Replication Progress Tracking

Added a progress meter for donor and joiner nodes in replication SST, visible in SHOW STATUS. This provides visibility into replication state synchronization progress.

Additional Improvements

LOCK TABLES support: Added for mysqldump compatibility
Buddy updated to 3.37.0: Various improvements and stability fixes

Bug Fixes

This release includes numerous bug fixes across multiple versions leading up to 14.1.0:

Critical Fixes

Fixed crash with max(ft field) - Resolved a critical crash when using max functions on full-text fields
Fixed empty filter name error - Resolved error when using filters with empty names
Fixed full-text query crashes - Addressed crashes caused by specific full-text query patterns
Fixed "(abc|def)" query handling - Full-text queries with this pattern now work as expected

Query and Search Improvements

Fixed HAVING total counts - Added ability to get total number of results for queries using HAVING
Enhanced CALL SUGGEST - SUGGEST can now use bigrams instead of trigrams when needed, improving spell correction for shorter words
Fixed CJK segmentation - Improved ParseCJKSegmentation when Jieba support isn't available
Added expansion phrase warning - New searchd.expansion_phrase_warning option for better query debugging

Replication and Clustering

Fixed replication transaction handling - Improved key generation and conflict resolution

System and Component Updates

Improved FreeBSD compilation - Fixed native FreeBSD build issues
Enhanced Filebeat compatibility - Added testing for Filebeat version 9.2
Better error handling - Improved error handling for right-joined JSON queries
KNN parameter validation - Added proper validation for KNN parameters

Compatibility

Manticore Search 14.1.0 maintains strong backward compatibility with important considerations:

General Compatibility

Fully compatible with existing data and queries

Replication Cluster Considerations

⚠️ Important: Version 14.0.0 introduced replication protocol changes. If upgrading from pre-14.0.0 versions with replication clusters:
